Name:
Named in honor of Josiah Parsons Cooke Jr. (12 October 1827, Boston, Massachusetts, USA - 3 September 1894, Newport, Rhode Island, USA), Harvard mineralogist and chemist. A largely self-taught chemist, he was one of the first Americans to teach laboratory chemistry. He made significant contributions to the measurement of atomic weights.
Isostructural with:
Characteristic botryoidal to worm-like aggregates show radial pattern of plates, occasionally showing pearly lustre of basal cleavage.

Forms a solid-solution series with (Li-free) donbassite.

A natural Na analogue may exist (see 'UM1969-13-SiO:AlHNa').
See also borocookeite.

Optical Data of CookeiteHide

Type:
Biaxial (+)
RI values:
nα = 1.572 - 1.576 nβ = 1.579 - 1.584 nγ = 1.589 - 1.600

Max. Birefringence:
δ = 0.017 - 0.024
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
